We shouldn’t just predict that a club will win the league due to the players they are signing, a club might end up spending huge amount of money on player, but the player might not be the perfect player which the club needs, so let’s wait and see how each team will perform at the beginning of the season.
But that's why Manchester United also needs new players that can be used for the UCL later not only in the domestic league, if we look back again at many clubs buying players we know not all of them will be good in the end so I also don't want to predict which a club that will win the league next season or become a great club, but here we see how they recruited many new players and were able to adapt quickly.
But for the performance of the next season, I retrained from making a vote now because we actually do not see the season yet or the performance of the clubs. It would take at least a full month for me to know which club would likely win the league. For now, those serious clubs I would be watching out for are Man City, Liverpool, Newcastle, Man U and Arsenal.
